A consecutive series of 112 primary uncemented total hip arthroplasties using the same type of prosthesis was reviewed for the incidence and severity of heterotopic ossification (HO). Sixty-three of these patients underwent a posterior approach (group 1) and 49 underwent an anterolateral approach (group 2). The two groups were virtually identical when risk factors, such as age, sex, estimated blood loss, length of surgery, and diagnosis were compared. Patients in group 1 had a significantly lower incidence and severity of HO than those in group 2. The overall incidence of class III or IV HO was very low (8%), indicating that uncemented total hip arthroplasty in itself is not predisposed to moderate or severe degrees of HO. Patients undergoing uncemented total hip arthroplasty through an anterolateral approach had a higher incidence of HO than those undergoing a posterior approach in this series.
对连续112例使用同一类型假体的初次非骨水泥型全髋关节置换术患者的异位骨化（HO）发生率及严重程度进行了回顾性研究。其中63例患者采用后入路（第1组），49例采用前外侧入路（第2组）。比较年龄、性别、估计失血量、手术时间及诊断等危险因素时，两组基本相同。第1组患者HO的发生率及严重程度显著低于第2组。Ⅲ级或Ⅳ级HO的总体发生率很低（8%），表明非骨水泥型全髋关节置换术本身不易导致中度或重度HO。在本系列研究中，采用前外侧入路进行非骨水泥型全髋关节置换术的患者HO发生率高于采用后入路的患者。
